This theme seems fine to me. It could use two or three minor changes though, that would improve it marjorly. Being: Change the font to something more 'round' like Open Sans or Robotico (Google Default) and to change the background. There seems to be a nice and calm colour palet with soft greens, whites, blues and greys. The 'hard' blue in the background ruins it. And lastly change the colour of the icons to be more black. Not completely black (never use 100% black or white), but not this either.

If you wish where I got my suggestions from and why they'll work, just Google: "Usability". It is the art of making things easy to understand and use.

Karma system could be nice. One major Dutch tech forum uses Karma points to buy stuff, like an add free website or special profile permissions. While That part might not be completely awesome, getting ranks or achievements for it, would.
